Abstract
Cotton yarns treated with polymenc sizing agents were studied by Fourier trans form infrared photoacoustic spectroscopy (FT-IR/PAS). Sizing agents on the yarn surfaces were identified by the use of spectral subtraction. The degree of penetration of the sizing agents into the yarns, the amount of sizing agents remaining in the yarns after desizing, and the hydrogen bonding between the sizing agents and the cotton cellulose also were investigated by FT-IR/PAS. In this research, the photoacoustic de tection demonstrated a variety of advantages over the conventional infrared spectro scopic sampling techniques.Keywords
